Petrifydisorients enemies for a long period of time, and deals damage when the disorientation ends. Ideally, you should attack other enemies, because if the petrified target receives enough damage, the disorientation will end early. More powerful enemies tend to be immune to the stun effect, but will still take damage. The Fossilize morph Immobilizes the target after the effect ends, while Shattering Rocks causes an explosion when the effect ends which will deal Physical Damage to all nearby enemies and set them Off Balance.
